Which of the following are major influences on weather and climate? i. the cycling of water in and out of the atmosphere ii. the physical weathering of rocks and soil iii. uneven heating of the earth by the sun's energy iv. global patterns of atmospheric movement a. i, iii, and iv only b. i, ii, and iv only. c. i, ii, and iii only d. ii, iii, and iv only

A. I, III, and IV only

Explanation:

The cycling of water in and out of the atmosphere is an important determinant of weather and climate. Changes in humidity and average rainfall usually depend on this factor.

Uneven heating of the earth by the sun also creates unique patterns of changes in weather and climatic conditions around the world.

Global patterns of atmospheric movement affect parameters such as wind speed etc.

the potential energy of the reactants is 200j.

from the energy diagram, the energy of the product formed is 350j; this means that, this reaction is an endothermic reaction, because it absorbs energy from its environment.

a 20-cm-long, cylindrical graphite (pure carbon) rod is inserted into an oxidizing atmosphere at 1145 k and 1.013 x 105 pa pressure. the oxidizing process is limited by the diffu- sion of oxygen counterflow to the carbon monoxide that is formed on the cylindrical surface.
